1 Claim.

5 solution within the bag.

It is an object of our invention to provide a nozzle which may readily be taken apart fr sterilizing, and which has a sufliciently large opening within the body of the nozzle to permit a cleaning brush to be used in cleaning the interna1 parts of the nozzle.

Another object of our invention is the provision of a nozzle having a hooded portion shapad to corresponcl With the body opening within which the nozzle is to be inserted.

It is our object to provide a nozzle which may readily be manipulated. for an irrigating douche in which the solution is retained for a desired interval. Another object is the provision of a nozzle which will permit the return flow of the solution together With any discharged matter removed from the parts irrigated without likelihood of stoppage of the return fiow.

Specifically, it is our object to provide a nozzle for a vaginal syringe in which the person using the syringe may retain a desired amount 01' fiuid within the Vagina at a desired pressure consistent With the static heac1 o1" liquid in the douche bag.

The above objects and other objects to which reference will be macle in the ensuing disclosure, we aocomplish by that certain combiriation and arrangement of parts of which We have illustrated a preferred embodimmt.

Referring to the drawing:

Figure 1 is a side elevation of the internal part o1" the nozzle.

Figure 2 is a p1an view of the nozzle hood.

Figure 3 a sectional view taken along the line 33 in Figure 2.

Figure 4 is a sectional view takten along a 1ine extending longitudinally through the nozzle assembly.

The nozzle is composed of an inner spray tube 1 having a passage 2 extending throughout its length. The tip of the tube is rounded as indicated at 3, and the discharge openings 4 are arranged in an annular groove 5 which prevents any tendency of the discharge orifices being blocked up by pressure of the parts of the body being irrigated against the openings.

The spray tube has a large circular flat fiange 6 formed integrally therewith, Which flange has a discharge opening 7 which extends through a tubu1ar projection 7a on the rear face of the fiange. Thema are bayonet lugs 8 also formed integrally with the tube.

The hood 9 for the spray tube is formed with an annular recessed channel 10 within which the fiange 6 fits, being hold therein by the engagement of the bayonet lugs 8 against spaced cam surfaced bosses 11 which are formed on the inner side of the hood 9. The shape of the hood 9 is preferably that of a hell e]liptical in cross seotion, so as to contact with the Walls of the Vagina so that there Will be no leakage.

When the spray tube 1 is inserted Within the hood and the douche is used, the cleaning fluid passes through the central tube out through the openings 4. The irrigation fiuid is then returned through the annulabr opening 12 between the internal tube and the hood, and passes out through the tubular projection 7a. It Will be obvious that pressure may be built up by placing the finger over the end of the tube 7a. When the parts have been dilated sufficiently, the finger may be removed and the solution, together With any discharge with Which the cleaning fiuid is contamin'ated, may be flushed out.

A washer 10a is used between the flanges 6 and 10 to make a leak proof joint.

The assembly may be readily taken apart by turning the flange 6 so as to release the bayonet look. As to size it will be obvious that for different types, or cleaning and sterilizing different parts of the body, the shape and size of the nozz1e may be changed. When anasal spray is desired, the size of the hood should be such as to accommodate itself to the shape of the opening in the nostril. So, for aural spraying, the size of the hood will be even sma1ler than for a nasal spray. For colon irrigation, the hood Will be larger to accommodate itself to the opening of the reotum.

The nozzle may be made 0:" any desired. material such as hard rubber, bakelite, or the lighter metals, such as aluminum.

Having thus described. our invention what we claim as new and desire to secure by Letters Patent is: 1

A douche nozzle comprising a drain casing With open inner anal outer ends and a nozzle tube extending through said casing ends and having an annularly extended flange fitting across the outer end of the casing, with a drain opening in said flange, the oppositely facing walls of the tube and casing, interiorly of the casing, having means coacting to clamp the flange across the end of the casing upon turning the tube and fiange relatively to the casing, said means having a passage for flow through the caslng.
